Hello everyone,
I am using the following code to try to calculate the mean :
dat<-read.table(file="C:\\Documents and Settings.....txt")
dat<-as.numeric(dat)
x1.m<mean(dat)
I am getting the following error message
Error in eval.with.vis(expr,envir,enclos):
(list) object cannot be coerced to type"double'
I do not understand what is wrong as I thought that I have changed
dat to a numeric.Whenever I list x1.m all I get are NA
Thank you
Paul
